To enhance the conversion efficiency of biomass CO(2)gasification and decrease tar, the experimental study of biomass pyrolysis and in-line catalytic CO(2)reforming (BPy-ILCCR) were investigated in a two-stage reactor. The prepared K-Ni/Al catalyst exhibits superior catalytic activity for gas products in BPy-ILCCR. Results show that both CO(2)concentration and temperature promote the rise of the gas production, but the increase slows down when CO(2)concentration is more than 40 vol%. At 700 degrees C, the gas yield andX(c)can reach 0.83 g/g-bio and 92.4%, respectively (40 vol% CO2, 3 g catalyst). The comparative study indicates that steam is slightly better for reducing liquid product under the same concentration of CO(2)and H2O, and theX(c)at 80 vol% CO(2)can reach 93.9%, close to the value obtained at 40 vol% H2O. Moreover, there exist similar quantities of coke deposition on the catalyst under the CO(2)and H2O atmosphere.
